Particularly when you take into account that, what does our military do: It defends our country.”

“These individuals have to be absolutely 100 percent loyal and trustworthy, as best as we can make them, 'cause they’re gonna have access to all sorts of military weaponry — even to the point of having access to weapons of mass destruction like our nuclear arsenal," Brooks said.

"And I’m gonna have much greater faith in the loyalty of an American citizen than a person who is a citizen of a foreign nation.”

Democrats refer to those young people, brought to the U.S. illegally by their parents, as "Dreamers" and have pushed for legislation to change their status.

In late May, the White House delayed a plan to allow a small group of these immigrants to enlist in the military in case Congress was able to pass immigration reform by the August recess.

Currently, immigrants who have work permits and don’t face deportation can enlist in the military through the Military Accessions Vital to National Interest program if they can provide certain medical and language skills.

President Obama has tasked Attorney General Eric Holder and Homeland Security Secretary Jeh Johnson with exploring ways to use executive actions to unilaterally fix the immigration system.
